Well, I first showed the comparables of worksheet prices. Envision student workbooks are actually about 100 less than Saxon refills. That first peaked administative attention.
I already create all of my worksheets/ assessments and lessons. I have been telling my principal for years to not even order me the refills. Yet $800 or so is wasted each year on my class.
Once they saw the comparables and all that I was doing was asking for the workbooks. I contacted the local rep, and she said she would just give me the sample teacher workbook to use for next year and the online demo program. So minus the manipulatives (which she said are similar to all of the items we have from Saxon) I will actually have pretty much an entire program that I am piloting that is going to cost less than Saxon refills.
I first talked to principal and then he talked to curriculum director and he okayed it. I did all of the other work so it was not at all a hassle for them.
